Definitions

  • the invention relates to a disc, in particular a side window of a motor vehicle with an electric and / or on the disc arranged electrical functional element, and a control device for driving the electrical functional element.
  • the mentioned electrical functional elements may be, for example, disk heaters or also devices for controlling the optical transmission of a disk.
  • the control unit for the said electrical functional elements is supplied with the usual on-board voltage of 12 volts. Since the functional elements themselves often have a higher voltage requirement, the voltage is converted in the control unit and forwarded via a high-voltage connection to the electrical functional elements.
  • the control unit is separated from the disk, so that the high-voltage component of the electrical interconnection must be routed via separate cable connections.
  • This has the disadvantage that just in side windows, which are to be designed to be movable, the cables of the high-voltage circuit must also be moved and are thus exposed to high wear.
  • Such a disk is disclosed, for example, in EP 1 256 261 B1.
  • the present invention is therefore the object of developing a disc of the type mentioned so that the connection of the electrical functional element is improved with the control unit and designed wear.
  • a retaining device for the control unit is provided on a window edge.
  • Control unit and electrical functional element are thus no longer spatially spaced.
  • the holding device for the control device is preferably provided on a lower edge of the window, which makes it possible to attach the holding device before mounting the side window.
  • the holding device preferably comprises a latching connection element for latching the control unit.
  • the reversibly releasable locking connection makes it possible in the simplest way to replace damaged control units without having to replace the entire pane.
  • the holding device further preferably comprises at least one electrical contact element for connecting the control unit to the electrical functional element.
  • the functions of the mechanical support of the control unit and the electrical connection of the control unit and electrical functional element are thus advantageously integrated in one component, so that no additional components are needed and weight can be saved. This, in turn, is of particular importance in the case of movable side windows, which are to be made as light as possible on account of their mobility.
  • the at least one electrical contact element is preferably designed for connecting a high-voltage output of the control device to a high-voltage input of the electrical functional element.
  • the electrical contact element may be formed as a cable connector.
  • the electrical contact element is particularly preferably configured as a latching connection between a contact surface assigned to the control device and a contact surface assigned to the holding device. This can be completely dispensed with cable connections in the high voltage circuit, so that the Risk of damage is minimized.
  • the high voltage circuit between the electrical functional element and the control unit is thus completely self-contained, it is only necessary to connect the control unit externally via a 12 volt line to the electrical system.
  • Fig. 1 is a schematic representation of an embodiment of a disc according to the invention.
  • FIG. 2 is a detailed view of a holding device with control unit mounted therein according to the embodiment of FIG. 1.
  • a designated as a whole with 10 disc, in particular a side window for a motor vehicle includes an electrical functional element 12.
  • This may, for example, a vapor-deposited on the disc 10 electrical resistance heating or a device for controlling the transmission of the disc 10 act.
  • the electrical functional element 12 requires a high-voltage supply which is made available via lines 14 likewise vapor-deposited on the pane.
  • the lines 14 terminate in contact plates 16 in the region of the lower edge 18 of the disc 10th
  • a holding device 20 is provided on the lower edge 18 of the disk in the region of the contact plates 16, which can receive a control device for the electrical functional element 12.
  • the holding device 20 is preferably made of plastic and glued to the lower edge 18 and surrounds at least partially the disc 10.
  • the holding device 20 has two locking elements 22, by means of which the control unit are reversibly attached to the holding device 20 can.
  • the attachment of a control device 24 in the holding device 20 is shown in Fig. 2 in detail.
  • the locking elements 22 engage in grooves 26 of the housing 28 of the controller 24 and hold it on the disc 10.
  • the control unit 24 requires no external high-voltage supply. Rather, it is connected via lines 30, 32 to the electrical system 34 of a motor vehicle and thus supplied with the usual 12 volt DC voltage. To connect this serve plug 36, which are received in corresponding sockets 38 of the controller 24.
  • the supplied from the electrical system 34 12 volt DC voltage is converted in a voltage converter 40 of the controller 24 in accordance with externally supplied control commands in the necessary for the operation of the electrical functional element 12 high voltage.
  • Via further lines 42 and arranged on the control unit 24 contact plates 44, the high voltage is provided to the electrical functional element 12.
  • the contact plates 44 come into coincidence with the contact plates 16 of the disc 10 and are pressed against them, so that the lines 42 of the control unit are in electrically conductive contact with the lines 14 of the disc 10.
  • the disk 10 is thus completely without moving high-voltage or AC power lines, so that even when moving the disc 10 damage to the high-voltage system is virtually completely excluded.
  • reversible recording of the control device 24 in the holding device 20 by means of the locking elements 22 allows easy replacement of the controller 24 in case of damage or in the case of a hardware upgrade.
